president, i could have been sitting in a private meeting with president obama. he would say it in english, not french, but he said the same thing. the president pointed out there's an obligation here that extends way beyond these administrations. >> biden says secretary of state john kerry will meet with the french foreign minister on the issue. some europeans have cheered kerry's confirmation that shows the united states is ready to affect climate change. the president promised to responsible to the threat of climate change but provided few specifics how. it's unlikely a large cap and trade will leave congress, leaving the president with the option of denying a canadian company's permit to build the keystone pipeline through the united states. the state department now under kerry's leadership has yet to approve or disease nye that pipeline's construction. >> want to battle climate change? think spring break. you heard me correctly. a new study out says you can affect global warming by cutting back on work hours like in europe. mark, just spell this out for me.
